iphone - Application gets crashed -

-

this question has answer here:

i using below code auto share on facebook in iphone application, application crashed exc_bad_access message, when tap share button. 

nsmutabledictionary *variables = [nsmutabledictionary dictionarywithcapacity:4]; [variables setobject:@"yours content shared" forkey:@"message"]; // share prepared content fb fb_graph_response = [fbgraph dographpost:@"me/feed" withpostvars:variables]; nslog(@"postmefeedbuttonpressed:  %@", fb_graph_response.htmlresponse);

help me out in advance.

it hard tell code provided, 1 idea:
dictionary variables created autorelease object. means if not retained in fbgraph, deallocated app returns main run loop, in tabbing share button handled. in case, variables no longer exists after button pressed, , exc_bad_access error.
if using arc, handled correctly compiler.
